Engine flushing

According to bpr you hook the water hose up and flush without running the the engine that didn't seem to be right to me being a former mechanic I asked the tech at th marina he agreed told me to tape off the front intakes use muffs and run the engine this ensures that all the water goes through the entire cooling system including the thermostats

Read your owners manual as you can run the motor to flush it while the garden hose is connected to the engine's flushing port

Re: Engine flushing

Just looked at the owners manual it does show that you can run engine but my owners manual shows you have to block off front intakes and use muffs

Re: Engine flushing

My dealer told me not to run the motor while the hose is connected to the flush port. It doesn't say it can be done in the manuel. I flush the motor not running with hose connected to flush port with Saltaway after using in saltwater , then I flush motor in my $180 Flush Bag that I ordered from California because I don't want a bunch of tape all over my motor.

Yes, you just answered your own question.

 

You can run the motor with the hose screwed into the flusher port OR you can use muffs as long as you tape off the holes in the nose of your gearcase or under the anti-ventilation plate. The taping off of the holes only applies to certain model engines whose gearcases have the extra intake holes.

 

Cliffb,

You did not give us the model number of your motor so we can only give you a generic response.

Re: Engine flushing

 

 

I see that you have a counter rotating engine.

 

Your motor has the 6 inlet holes in the nose of the gearcase, use a wide piece of painters tape to cover them if you use a muff type of flusher. Painters tape does not leave a sticky residue like duct tape does.

Re: Engine flushing

I have model number E75DPLABA, what do I do, what's the proper way to hook up muffs? When I first got my motor last year I bought the best muffs I could find and attempted to flush motor. I have good water pressure but I never got water to discharge from the motor. I called my dealer and he said that I needed to flush the motor thru the port not running or in a Flush tank only. I know I would love to flush my motor with muffs while running.
I can tell you, this is very confusing for me.

Pages 58 and 59 of your operators guide illustrate how to use muffs for flushing your Evinrude E-TEC 75 HP.

 

A quality set of dual feed muffs are the best to use and have to completely fit over the intake screens of the gearcase and have adequate water flow and pressure-  20-40 psi. Follow the directions in your  manual. It does take up to about 30 seconds or so after starting for the engine block to fill with water and to exit the tell-tale

 

Dual Feed Flusher from Amazon:

 

Dual Feed Moeller Flusher
